Slide magazine

Abstract

A slide magazine for slide frames having a peripheral edge with a peripherally extending groove on the two faces thereof and a notch at at least one edge portion of the peripheral edge, comprises a base portion with longitudinally spaced pairs of transverse rib portions. The rib portions of each pair are disposed in alignment transversely to the base portion and each pair is spaced from an adjacent pair to provide a slide frame-receiving compartment. The rib portions carry retaining ribs to hold the respective slide frame in a spill-resistant manner in the slide magazine, and each rib portion further has a projection for engaging into the groove to hold the respective slide frame in its compartment. A resilient finger in the base of each compartment has a retaining nose to engage into the notch of the slide frame to hold it in position. Slide frames can thus be inserted into and removed from the slide magazine at both sides thereof.

What is claimed is: 
     
       1. In a slide magazine for slide frames having a peripheral edge having peripherally extending grooves and a notch at the peripheral edge, the slide magazine comprising: a base portion; transverse ribs disposed on the base portion and spaced from each other to form compartments for accommodating respective slide frames, each transverse rib having at least one projection which projects laterally therefrom and is adapted to engage into a groove of the respective slide frame; spaced-apart resilient fingers arranged on the base portion, each finger being associated with a respective compartment and having an upwardly projecting retaining nose for engagement into a notch of the respective slide frame; and retaining ribs disposed on the base portion and projecting upwardly therefrom in alignment with the transverse ribs for holding the respective slide frames in a spill-resistant manner in the slide magazine; the improvement that the slide magazine is provided with transverse ribs arranged on said base portion in a transverse direction and separate from each other, and between which are disposed corresponding retaining noses of respective compartments; the retaining noses being aligned with each other in a longitudinal direction of the slide magazine and defining an axis of symmetry along which the transverse ribs are arranged, each transverse rib being disposed in a transverse direction to said axis of symmetry, said upwardly projecting retaining ribs being arranged on said transverse ribs to either side of said axis and providing common outside edges with said transverse ribs, said outside edges having a knife-edge configuration. 
     
     
       2. A magazine as set forth in claim 1 wherein each retaining rib as measured in the transverse direction of the slide magazine is of a widthwise dimension which is smaller that the length of the corresponding transverse rib, whereby said transverse rib has a region having an associated retaining rib and a region free of a retaining rib. 
     
     
       3. A magazine as set forth in claim 2, wherein each transverse rib has first and second spaced-apart projections arranged on each side and projecting therefrom one being in the region of the associated retaining rib and the other in the region of the transverse rib which is free of the retaining rib. 
     
     
       4. A magazine as set forth in claim 3 wherein each projection in the region of the associated retaining rib has a bevel at an end part facing an outside edge of the transverse rib portion and the retaining rib. 
     
     
       5. A magazine as set forth in claim 4 wherein each said projection which is disposed in the region of the associated retaining rib is displaced inwardly of the slide magazine relative to the corresponding outside edge of the transverse rib and the retaining rib. 
     
     
       6. A slide magazine for slide frames having a peripheral edge having peripherally extending grooves and a notch at at least one edge portion of the peripheral edge, the slide magazine comprising: an elongate base portion; a plurality of rib means which extend transversely of the base portion and which are disposed at spacings from each other in the longitudinal direction of the base portion to form compartments for accommodating respective slide frames, each said transverse rib means comprising first and second rib portions which are separated from each other in the transverse direction of the base portion and each transverse rib portion having at least one projection which projects laterally therefrom and which is adapted to engage into said groove configuration of the respective slide frame; a plurality of resilient fingers disposed on the base portion at spacings from each other in the longitudinal direction of the base portion, each finger being operatively associated with a respective compartment; a retaining nose on each said resilient finger and projecting away from said base portion for engagement into said notch of a respective slide frame, the retaining nose of each compartment being disposed between the respective rib portions thereof and the retaining noses being aligned with each other in the longitudinal direction of the slide magazine to form an axis of symmetry along which the transverse rib portions are arranged; and retaining ribs disposed on respective oppositely disposed transverse rib portions and aligned therewith and projecting away from the base portion for holding the respective slide frames in the slide magazine in an at least substantially spill-resistant manner, said retaining rib and associated rib portion having a common outer edge having a knife-edge configuration. 
     
     
       7. A magazine as set forth in claim 1, wherein said transverse ribs and associated retaining ribs define said compartments having outwardly facing open ends on each side of said axis of symmetry, whereby respective slide frames can be inserted into sand removed from respective compartments from either of said open ends.
